Victory for the All Blacks this weekend could lead to a mini baby-boom.
When the All Blacks lifted the Webb Ellis Cup in June 1987, a brief baby-boom followed nine months later.
Statistics NZ figures show that in March 1988 there were 4822 births - almost 400 births more than in February and April.
All other tournaments - barring the 2003 cup when the All Blacks lost to Australia 22-10 in the semifinal - also resulted in an increase in births, though much smaller, nine months later when compared with the previous month.
The smallest increase was 20 babies, and came nine months after the All Blacks' shock exit in the quarter-finals against France at the 2007 World Cup.
